摘要：

最近报道的双玻色子和双光子过剩在大型强子对撞机被解释为与重$WW$零自旋共振。共振的出现是由于弱玻色子的反常三重相互作用，这是众所周知的耦合常数$λ$定义。$2\, TeV$异常初步对应于弱同位素自旋2标量态，而$γγ\,\,750\, GeV$异常对应于弱同位素自旋0赝标量态。我们得到的效果，定性同意ATLAS数据的估计。通过共振$X_{PS}$与$M_{PS} \simeq 750\,GeV$，可以可靠地检查在升级的大型强子对撞机在$\sqrt{s}\,=\,13\, TeV$生产$W^+ W^-, (Z,γ) (Z,γ)$的影响进行预测。在三重反常相互作用的自发产生的方法的框架内，其耦合常数估计为$λ= -\,0.02\pm 0.005$与现有的限制协议。该假设的具体预测是衰变通道$X_{PS} \to γ\,l^+\,l^-\,, X_{PS} \to l^+\,l^-\,\,l^+\,l^-\,(l = e,\,μ)$中的显著效应。

英文摘要：

Recently reported diboson and diphoton excesses at LHC are interpreted to be connected with heavy $WW$ zero spin resonances. The resonances appears due to the wouldbe anomalous triple interaction of the weak bosons, which is defined by well-known coupling constant $λ$. The $2\, TeV$ anomaly tentatively corresponds to weak isotopic spin 2 scalar state and the $γγ\,\,750\, GeV$ anomaly corresponds to weak isotopic spin 0 pseudoscalar state. We obtain estimates for the effect, which qualitatively agree with ATLAS data. Effects are predicted in a production of $W^+ W^-, (Z,γ) (Z,γ)$ via resonance $X_{PS}$ with $M_{PS} \simeq 750\,GeV$, which could be reliably checked at the upgraded LHC at $\sqrt{s}\,=\,13\, TeV$. In the framework of an approach to the spontaneous generation of the triple anomalous interaction its coupling constant is estimated to be $λ= -\,0.02\pm 0.005$ in an agreement with existing restrictions. Specific predictions of the hypothesis are significant effects in decay channels $X_{PS} \to γ\,l^+\,l^-\,, X_{PS} \to l^+\,l^-\,\,l^+\,l^-\,(l = e,\,μ)$.
